The late blight network was first established in 1993 to help the potato and
tomato industry respond effectively to the potential for serious epidemics of
late blight caused by newly introduced Ridomil resistant isolates of Phytophthora
infestans. The goal of this ongoing project is to minimize crop losses caused
by late blight by educating growers about the importance of sanitation and timely
applications of protective fungicides, providing Extension field staff with
access to weather data and late blight disease forecasts, providing growers
with information on late blight inoculum levels and how favorable the weather
has been for late blight epidemic development, and keeping the industry informed
about the occurrence and severity of late blight throughout NY and in adjacent
states and Canadian provinces.
